Old cars unreliable?
http://adcache.collectorcartraderonl...8/32575048.htm
For less than $5,000 you get a Nova (SS at that!) with a all new drive line... Engine, tranny, posi rear end. And if you're wanting EFI aftermarket companies make adaptors... so what? another $1,000 to $2,000 and you've got a reliable old car with EFI. Just change the rear end from 4.10's to like 3.55's to save gas but retain good pick up and go.
Chargers, and any Mopar for that matter are expensive to buy and build.
i've never heard of a 380 mopar motor.. i think you're thinking of the 383

.

Here's your beloved RJ 350

$4800 is kinda steep for the power it doesnt make...

the ZZ4 350 makes slightly more power and is $3600.
I'd go with the ZZ4 350, and upgrade to the EFI at a later time.
Or... a Fast Burn 383 with LT4 Cam 430hp 430ft-lbs ... but you pay the price.. $4900

the possibilities are endless... but if you look around you can always find somebodies near finished project car... for cheap!
